<p>I notice that there's a lot of crates in <a href="http://perf.rust-lang.org">perf.rust-lang.org</a> but also a lot of synthetic stress tests. I am trying to find where the contents of those are located or just in general short explanations for them and am having a bit of trouble. Is there anywhere those are explained?</p>
